Hi Kambiz,
You are pretty close... you can use getIsisSessionFactory().doInSession(...)
there's an example in the RegisterPanel, a component of the Wicket
RegistrationPage.html / .java [1], ie:
getIsisSessionFactory().doInSession(new Runnable() {
@Override
public void run() {
final UserRegistrationService userRegistrationService =
getIsisSessionFactory()
.getServicesInjector().lookupService(UserRegistrationService.class);
getIsisSessionFactory().getCurrentSession().getPersistenceSession().getTransactionManager()
.executeWithinTransaction(new TransactionalClosure() {
@Override
public void execute() {
userRegistrationService.registerUser(userDetails);
removeAccountConfirmation();
}
});
}
});
HTH
